  • The Corps reminds everyone to practice water safety

    ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, wants to remind everyone about the importance of practicing safe, responsible and thoughtful activities in and around the water Memorial Day weekend.

  • Beneficial Use of Dredged Material in the Atlantic Intracoastal Waterway: Approaching the Regulatory Process

    Purpose: Following the Chief of Engineer’s January 2023 goal to expand the beneficial use of dredged material (BUDM), the US Army Corps of Engineers (USACE) strives to apply new and creative ways to increase utilization of dredged materials from a historic 30%–40% to 70% by 2030. As USACE Savannah District (SAS) increases BUDM efforts, a critical component of this transition is understanding and navigating the regulatory requirements. This Technical Note outlines the regulatory process for placement of dredged material in Georgia, identifies challenges and institutional barriers, and offers potential solutions to streamlining the overall process. By increasing the ease of navigating the regulatory process, USACE can facilitate an increase in BUDM and Engineering with Nature® (EWN®) projects in Georgia, and potentially other projects employing nature-based solutions (NBS). While regulatory details may vary from state to state, the Georgia example presented here can serves as a road map for the general types of regulatory procedures and potential hurdles found nationwide.

  • Army Corps hosts Albeni Falls Dam public information meetings May 30-31

    Army Corps of Engineers is hosting public meetings May 30 in Ponderay, Idaho, and May 31 in Cusick, Washington, to inform the public on current restricted operations at Albeni Falls Dam.

  • NAVIGATION NOTICE Number SWL 24-44 SAILING INSTRUCTIONS

    Due to shoaling, mariners are advised that until further notice, both upbound and downbound tows should stay on the charted centerline from NM 221.2 to NM 221.7.

  • Contract awarded for levee work for the West Shore Lake Pontchartrain project

    The U.S. Army Corps of Engineers, New Orleans District, recently awarded a contract for constructing the ninth reach including levee, floodwall and a gate on the West Shore Lake Pontchartrain (WSLP) Hurricane and Storm Damage Risk Reduction project. This contract will construct approximately 1.1 miles of the 18.5-mile-long levee system that will provide 100-year level risk reduction to the area primarily in St. John the Baptist, St. James and St. Charles Parish.

  • Low Sill Control Structure: Physical Modeling Investigation of Riprap Stability Downstream of End Sill

    The model investigation reported herein describes the process to model and analyze the stability of scaled riprap in the existing 1:55 Froude-scaled Low Sill Control Structure physical model. The existing model is a fixed-bed model, so modifications were made to create a testing section for the scaled stone. Three separate gradations of scaled riprap were tested at varying boundary conditions (discharge, head and tailwater elevations, and gate openings). Each test was surveyed using lidar for pre to posttest comparisons. It was found that Gradation B remained stable throughout the tests in the physical model.

  • Lessons in Rearing Mealworms for Plastics Degradation

    Purpose: The primary objective of this research is to determine if plastics-degrading gut bacterial communities from a nonoptimal insect host can be successfully transplanted into the gut of the optimal mealworm host for large scale composting. To achieve this goal, foundational questions about basic mealworm husbandry needed to be addressed, including proper housing and feeding regimes, expected plastics degradation rates, and survivability on plastics as a food source. This technical note serves as a mealworm husbandry protocol and a guide for lessons learned in the early stages of experimentation dealing with establishment of plastics-degrading mealworm colonies.

  • Engineering With Nature: An Atlas, Volume 3

    Abstract: Engineering With Nature: An Atlas, Volume 3 showcases EWN principles and practices “in action” through 58 projects from around the world. These exemplary projects demonstrate what it means to partner with nature to deliver engineering solutions with triple-win benefits. The collection of projects included were developed and constructed by a large number of government, private sector, nongovernmental organizations, and other organizations. Through the use of photographs and narrative descriptions, the EWN Atlas was developed to inspire interested readers and practitioners with the potential to engineer with nature.

  • CTX receives funding in FY24 Work Plan

    The U.S. Army Corps of Engineers (USACE) allocated the first installment of federal funding toward the USACE Galveston District’s (SWG) Coastal Texas Project (CTX).
